BQ24703PW - TI Function Overview

The BQ24703PW is a highly integrated Battery Charge Controller and System Power Selector uses dynamic power management (DPM) to minimize battery charge time by maximizing use of available wall-adapter power. This is achieved by dynamically adjusting the battery charge current based on the total system (adapter) current. It also uses a fixed frequency, pulse width modulator (PWM) to accurately control battery charge current and voltage. Charge current limits can be programmed from a keyboard controller DAC or by external resistor dividers from the precision 5V, ±0.6%, externally bypassed voltage reference (VREF), supplied by the charge controller. The battery voltage limit can be programmed by using the internal 1.196V, ±0.5% precision reference, making it suitable for the critical charging demands of Li-ion cells.
